First Record of Stegosaur (Ornithischia, Dinosauria) from the Aptian–Albian of Mongolia

  title={First Record of Stegosaur (Ornithischia, Dinosauria) from the Aptian–Albian of Mongolia},
  author={T. A. Tumanova and Vladimir R. Alifanov},
  journal={Paleontological Journal},
The first Mongolian stegosaur, Mongolostegus exspectabilis gen. et sp. nov., Stegosauridae (Ornithischia), represented by a series of anterior caudal vertebrae and bones of the pelvic girdle is described. The vertebral structure and massiveness and morphological features of pubic bones provide a unique combination of features, allowing recognition of diagnostic characters. The new taxon comes from the Aptian–Albian deposits of the Khamryn-Us locality (Mongolia) and belongs to the latest… 

Two new stegosaur specimens from the Upper Jurassic Morrison Formation of Montana, USA

Two partial skeletons from Montana represent the northernmost occurrences of Stegosauria within North America. One of these specimens represents the northernmost dinosaur fossil ever recovered from

Wear patterns and dental functioning in an Early Cretaceous stegosaur from Yakutia, Eastern Russia

The combination of high degree of tooth wear with formation of multiple wear facets, complex jaw motions, relatively short tooth formation time and possibly high tooth replacement rates is interpreted as a special adaptation for a life in high-latitude conditions or, alternatively, as a common stegosaurian adaptation making stegosaurs a successful group of herbivorous dinosaurs in the Middle Jurassic–Early Cretaceous and enabeling them to live in both low- and high-Latitude ecosystems.

The influence of juvenile dinosaurs on community structure and diversity

It is demonstrated that juvenile megatheropods likely filled the mesocarnivore niche, resulting in reduced overall taxonomic diversity, and suggests that ontogenetic niche shift was an important factor in generating dinosaur community structure and diversity.

In 1988, an incomplete skeleton of a stegosaurian dinosaur was found in Lower Cretaceous strata of the Ordos Basin of China by the Dinosaur Project (China – Canada – Alberta – Ex Terra). The material

Limb-bones.—Since the humerus is known in Hylœsaurus (?), Omosaurus, and Stegosaurus, it is quite easy to compare the humerus of our new species with that of the other genera mentioned. Whether the

First definitive stegosaur from the Middle Jurassic of Kyrgyzstan

Four articulated posterior dorsal vertebrae from the Middle Jurassic (Callovian) Balabansai Svita at Sarykamyshsai locality in the northern Fergana Valley represent the first record of Stegosauria in

Systematics and phylogeny of Stegosauria (Dinosauria: Ornithischia)

A cladistic analysis of Stegosauria (the first to be based upon direct observation of all relevant specimens) is presented, which indicates that Tuojiangosaurus, Loricatosaurus and Paranthodon are sister taxa to Stegosaurus.

New Archosaurs from the Jurassic of Siberia and Mongolia

New finds of crocodiles and dinosaurs from the Late Jurassic deposits of southwestern Mongolia (Shar-Teg locality) and Eastern Siberia (basin of the Vilyui River, Teete locality) are described. A new

Stegosauria: a historical review of the body fossil record and phylogenetic relationships

A new phylogeny, which includes all valid stegosaurian taxa, largely agrees with previous studies and shows the European Dacentrurinae was sister taxon to Stegosaurus.

Juveniles of the stegosaurian dinosaur Stegosaurus from the Upper Jurassic of North America

ABSTRACT Two partial skeletons of juvenile individuals of Stegosaurus with estimated body lengths of about 1.5 m (5 ft) and 2.6 m (8.5 ft) are described from the Morrison Formation (Upper Jurassic)

Stegosaur remains from the Middle Jurassic of West Siberia

The Middle Jurassic (Bathonian) Itat Formation at Berezovsk Quarry, Krasnoyarsk Territory (West Siberia, Russia) has produced abundant remains of stegosaurs. Numerous isolated teeth are found at

A review of the Late Jurassic stegosaurs (Dinosauria, Stegosauria) from the People's Republic of China

This taxonomic revision significantly reduces known stegosaurian diversity worldwide, and shows that the Chinese diversity was similar to that of Europe and North America in the Upper Jurassic.


The plesiomorphic status of Huayangosaurus suggests that substantial convergence between ankylosaurs and stegosaurs occurred during their respective evolutionary histories, reflecting coincident functional morphological changes associated with the adoption of obligate quadrupedality.
